go-collections

Golang collection types using Generics. Also includes common collection operations for existing types like slices.

Collection Types

1. Set
2. Counter
3. Slice

Set

A unique set of Comparable values. Set's are useful for quickly getting the unique values of a slice and performing set operations such as

• Difference
• Union
• Intersection
• Complement

There are also utility functions for using set operations with slices. These helpers follow the syntax SliceUnion, SliceIntersection, etc.

Counter

A map that contains the counts of Comparable items. Counters can be created from

• Maps where the value is an int.
• Slice where the number of times an item is repeated is the count.
• String where each character is parsed as an item.

Some useful methods of counters include

• MostCommon - get the most common element
• MostCommonN - get the N most common elements
• AddCounter/SubtractCounter - add/subtract one counter from another

Slice

Slices are a built in type in Go, but this package includes some utility functions for slices that are not built in. These include:

• Unique - get the unique values of a slice
• Contains - check if a slice contains a value
• Filter - filter a slice based on a predicate
• IndexOf - get the index of a value in a slice
• Map - apply a function to each element of a slice
